UNITED STATES WILLIAM PETERSEN AND CHARLES D. MILLER, OF CHICAGO, ILLINOIS.

SMOKE QON'SUMER.

Application filed-November 22, 1921. Serial No. 517,000.

This invention relates to smoke consumers especially designed for locomotives and has for an object the provision of means where by the products of combustion which ordlnarily pass off to the atn'iosphere, will be consumed, and thereby increase the efficiency of the locomotive and reduce its fuel consumption.

The present invention, is an improvement upon an application filed by us October 13, 1921, Serial No. 507,615 and like this patent provides means whereby the above stated objects may be accomplished through the use of waste energy furnished by the locomotive, so that the power generated by the latter will not in any manner be reduced,

by the supply of energy used for the operation of the invention.

Another objectof the invention is the provision of means for supplying fresh air in a preheated state to the fire box of the locomotive and thus furnish a proper amount of oxygen without reducing the temperature of the boiler, the preheated air being conducted through the part of the boiler whose temperature is usually lowest. This assists in raising the temperature throughout the boiler.

Another object of the'invention is the provision of means for directing the smoke and gases inwardly or toward the center and be neath the baflie wall of the fire box, so that the products of combustion are thoroughly consumed and the consumption of fuel thereby reduced, means being also provided whereby this action may be increased as desired.

With the above and other objects in View, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claim.

In the drawings Figure 1 is a side elevation showing diagrammatically a portion of a locomotive with the invention applied thereto, parts being broken away and others shown by dotted lines.

Figure 2 is a front view of the same.

Figure 3 is an enlarged side view of the air intake pipe, the latter being partly shown in section and illustrating means for supplying steam to this pipe.

Figure 1 is an enlarged transverse sectional view through the air intake pipe illustrating the arrangement of the steam nozzles therein.

Figure 5 is a section showing distributing nozzles in one of the pipes 11.

Figure 6 is an enlarged sectional view illustrating the position of the steam nozzles with respect to the walls of the fire box.

Referring to the drawings in detail, wherein like characters of reference denote corresponding parts, the reference character 10 indicates the boiler of a locomotive, of the usual or any preferred construction, the invention like that disclosed in the applica tion above mentioned, being applicable to locomotives of any make, without changes in structure, or in any manner weakening any of the engine parts.

As previously stated, it is the purpose of the invention to supply fresh air to the fire box of the locomotive, in a preheated state and to confine-this air and the products of combustion within the fire box, until the latter are thoroughly consumed and to accomplish this the draft is created from a point in advance of the boiler fines of the locomotive and travels rearwardly into the fire box for the supply of a proper amount of oxygen. For this purpose there is provided upon opposite sides of the locomotive boiler between the smoke stack and the forward end of the boiler flues, an air intake pipe 11. These pipes are identical in construction and enter the boiler at the point mentioned and their combined diameters are substantially the same as the diameter of the smoke stack. The intake ends of the pipes 11 are formed of oppositely extending branch pipes 12 and 13, whose combined diameters are substantially the same as the diameters of eachof the pipes 11. The-pipe 12 has its open end extending forward, so that during the forward progress of the locomotive, air will be sucked into the pipes 11 through the pipes 12 and the suction thus created will provide a suction in the pipes 13, and thus drawin additional air. lVhen the locomotive is moving in a reverse direction, these conditions will be reversed, that is, the pipes 13 will scoop in the air and additional air will be drawnin through the pipes 12.

The inner ends of the air intake pipes 11 extend downwardly toward the center of the boiler and are in communication with rearwardly extending pipes 14, theilastmentioned pipes extending backward and having their inner open ends disposed adjacent a baffle plate 15. The pipes 14: thus conduct air which enters through the intake pipes 11, rearwardly into the fire box beneath the usual baflle wall 16. The wall 16 is provided with an opening to permit air from the pipes 14 to enter the fire box into which it is deflected by the plate 15.

For the purpose of preventing cooling the fire through the introduction of cold air through the pipes 14, each of the air intake pipes 11 is provided with a coil 17 which receives steam from the dry pipe 18 of the locomotive, through pipes 19. The size of the coils 17 is so regulated, that air entering through the intake pipes 11 will be heated during its passage through said pipes and will be delivered to the nrc box in a preheated state. As the pipes 14 are arranged along the bottom of the boiler 10 be neath the boiler Hues, this portion of the boiler, which is usually the lowest in temperature, is heated, so that the arrangement also assists in maintaining proper temperature in the boiler.

Steam is also supplied to the air intake pipes 11 through pipes 20, the last men tioned pipes conducting exhaust steam from the steam chests upon each side of the locomotive. This supply of steam from the steam chests acts to increase the draft through the air intake pipes l1 and the pipes 14. If desired, the supply of steam may be increased through an additional. steam pipe 21, which may receive steam from any suitable point.

Each of the pipes 20 and 21 is provided with a distributing nozzle 22 having an arcuate slot 22 so as to more evenly distribute the steam throughout the area of the pipes 11 and in addition aid in heating the air passing therethrough, so that the purpose of the steam entering the pipes 11 is to both increase the draft and aid in preheating the air. I

One of the novel features of the present invention resides in the provision of means whereby the exhaust steam may be utilized for the purpose of confining the products of combustion within the fire box until they are thoroughly consumed. To accomplish this exhaust steam is taken from the steam chests and conducted into the fire box around the walls of the latter. This may be accomplished in various ways, the present method being to connect the pipe with each of the pipes 20 upon opposite sides of the boiler. The pipes 23 extend rearwardly and are connected by a cross pipe 24: and this last mentioned pipe and the adjacent portions of the pipes 23 are provided with nozzles which extend inwardly toward the Walls 26 of the tire box and are slightly spaced from openings provided in the latter. The steam is thus conducted around the sides of the fire box Without reducing its area or in any manner interfering with proper firing ot the locomotive.

Steam from the nozzles is projected into the fire box so that the products of combustion are driven from the walls toward the center beneath the battle wall 16 and are confined beneath this wall until they are thoroughly consumed. This not only prevents the escape of smoke and gases to the atniospl'iere through the smoke stack of the locomotive, but materially reduces the fuel consumption of the latter.

if desired, the amount of exhaust steam supplied to the fire box may be increased from the dry steam pipe 18. For this purpose there is connected to each of the pipes 2 upon opposite sides of the boiler, a pipe 2?, one of said pipes extending over the top of the boiler as at 28 for connection with the other pipe, while the last mentioned pipe is in communication with the dry steam pipe as shown at A valve 30 is provided in the last n'ientioned pipe between the point of connection with the dry steam pipe 18 and the point of connection with the pipe '28 and this valve is provided with a rod 31 which extends rearwardly to within convenient reach of the locomotive driver, whereby the said valve may be conveniently controlled. A valve 32 may also be pro vided in each of the pipes 28.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claim.

Having described the invention what is claimed is A; smoke consumer for locomotives comprising pipes curved at right angles upon themselves and passing through the walls of the locomotive adjacent the front end thereof with the outer ends of said pipes open to the atmosphere, a battle plate in the fire box of the locomotive and disposed in the path of the inner ends of said pipes, steam coils arranged in said pipes at the point of juncture of said pipes with the walls of the locomotive, means for supplying steam from the steam chest of the locomotive to said coils for preheating the air passing through, said pipes, steam pipes tern'iinating in the-pipes first mentioned and in juxtaposition to the coils to increase the draft through said pipes first mentioned, and arcuate shaped nozzles on the steam pipes, and said nozzles being formed with slots shaped to follow the curvature of the nozzles.

In testimony whereof we atfix our signatures.
